Y This invention'relates to' fabric measure'v ing' and' examiningvmachines of a class in which afmeasuringrwheel forming a part of themeasuring or indicating meansrests against the fabric., which is`suitably sup! ported while Vbeingy advanced.

According to onenovel feature of the invention, 4the'measuring means 1sheld pressing against the-fabric and the latter is supported in suchawaythat the wheelof the measuring means can fdrnn a` depression: orbulgein the fabricr so that the wheel btains adequate traction forcausing its*l rol tation bythe fabric, which it could not vdo `if the,fabric'ifs verythin and'is supported.4 fiat on a'tableor other smoothsurface,' under whichcondition'bouncing of the wheel would result inafalse lreckon-ing ,To reduce the vibration of',` the' -wheel toward and.from theffabric as. thel resultfof rapidladvvance offth'e fabric,V thusstea'dying the I neasur-4 ing rfmeans, preferably provide a fabricySupport arranged to bear against the same suo side of.v

he 'fabric as that with which the The machine is intended to operate onvery delicate and quitejsheer kfabrics which are likely topuckeny orwrinkle asV the result of the resistancefoffered :by the wheel. I

thereforeV provide means to guidel the pory tion ofthe fabric engaged bythe wheelin a substantially horizontal plane and between the .fabricadvancing-means and the guiding means andV arrangedk higher than thelatter I .place other means toguide the fabric in substantially ahorizontal, planefthislatter.`

i means vbeing usefull'in' the lexaminationof the fabric and alsocoacting with the first guiding means tomaintain the fabric trans-lversely stretched tso that it cannot pucker VV'underthe draft of thewheel.

base for the machine" frame is indicated in dotted lines at labeing hereillustrated as stored. On this .base rests va table which aV safe inwhich the Vjfabric (silk) may be projects .at both ends y(seegFig. l).It is j l preferred that -this vtable be extensible later-` 'ally (or asviewed `from the right or left in vFig.A for thisj purpose it includesarnain portionQ andy a lateral sliding `portion or leaf 3.,'Vvoperatively connected as will appear. V-

VAt both sides ofrtheright hand end of the table in Fig. lare securedbrackets`4 4 which are counterparts of each other excepting that vtheone l,at the left in Fig. 2fhas a depending ,extension 4"; atV bothsides of the left V*hand* y,end of the table inFig. lare securedvbrackets y5 5, which'are counterparts, of each other.

.The .bracket-si 4 and 5` on eachside Vofthe table are cc'nlnected by abrace structure 6 (Figsll and'). 1The` bracket 4 which is securedto theleaf?) and a bracket 7 which depends from thefleaf at theleft hand end fthereof in Fig.,l` are secured on horizontal transverse shafts 8 whichAare .telescopically movable 1n transverse horizontal tubes or .pipes 9which are secured to the'under side n of the part2 of the table; thusthe table -Inay v.be extended laterally and when the leafhas been'adjusted .to any lateral. positionV itr may be secured by set-screws10.- i y in the pipes 9 arranged to bind against vthe fshafts V8.

Thevbrackets afford bearings .forvthe 'gudgeons ofthe beam. -`11`onlwhich thel fabric. A to.' be measured iswound.v `This Vbeam isarranged` above the table and the fabric then'extends down :under vatransverse froller. -12 journaled in .theA brackets 5 Vand forming aguide for lthe fabric. Tn the brackets 4 'is vjournaled anothertransverse roller 13 forming' aY guide underwhich the fabric extends.

Theguides 12 and 13 are arranged at such an elevation that there isappreciable 'clearance between the fabricv and the top of the tablevwhen the former is held Ysrs .l a counterweight.

taut, as when it is being drawn and thereb advanced in the measuringoperation. n rom the guide 13 the fabric extends up and over theexamining table 14 formingaguide arranged at anrappreciable elevationvabove guide 1.3 and preferably inclined downward toward the right handend of the machine lin Fig. 1. Near its upper end this examiningboard'has on its underside hooks 15 adapted to catch over a bar 16 whichis supported at its ends by two posts 17 vertically adjust-able in studs13 that are swivelled in the upper ends of the brackets 4, the postsVbeing adapted to be held where vertically adjusted by set-screws 19andthe swivelled studs being adapted to be held where rotatablyadjustedby adjusting nuts 20. The bar 16 may be telescopic, the tubularportionthereof 16' being carried-by one post 17 and'the'received portion 16"'bythe other post 17. The inclined board 14 rests at its lower end o n oneof the two brace rods y'2lwhich connect the two bracket-s 4.

The two brace structures 6 are connected bya bar (22) which may betelescopic, the

tubular part 22 being connected to one brace` structure and the receivedpart 22 tothe other brace structure. S'uitably secured to the tubularpart of this telescopic bar is a forked-shape bracket 23 in -the arms ofwhich is pivoted` on a horizontal axis'a forked frame lever 24 havingan, arm 24 on which is adjustablelengthwise thereof a weight 25. Thearms of the forked lever 24 afford bearings for the spindle of themeasuring wheel26, as t0 `which 25 forms Said'spindle has aworm y V27thereon in Vmesh with the worm-wheel 28 (Fig. 7) on a vertical shaft 29journaled in' a bracketl 30 mounted on lever-24; at the v top thebracket affords a'horizontal bearing for the rotary pointer 31 connectedby beveled gearing 32with the shaft 29, lthere being fixed ona bracket24 a dial 33 to coact When the wheel 26 is rotated thepointer rotateswith respect to the dial.

The wheel bears on the portion A of the fabric A which bridges theguides 12, 13 and to a certain extent bulges the fabric by its `pressure(Figs. 5 and 6) this results in the wheel having appreciable contactwith the fabric and so a good tractive grip thereon.

'The tablcis placed under the portion A.

principally torsupport it atvthe time when thefabric slackens for anyreason. A

VVhenthe fabric -is being advanced the wheel would undergo someundesirable up and down vibratory movement unless it were cont-rolled.`I therefore prefer' to provide a fabric support 34'which bears againstthe top of the fabric ,and is preferably a blade Vapertured-or slotted,as at 34', to receive the wheel. This'blade is fixed, as by rivets 35,to the back of the bracket 23 and extends follows: Inhthe brackets 4 isjournaled the receiving beam 38. An Yelectric motor 39 is`mountedonthefunder side of the table and through a belt and pulleysystem 40 it 1 Adrives a countershaft 41 (Fig 2). rIhrou'gh a clutch 42this countersliaft drives an ex-V tension shaft 43. rIhe shaftc43 drivesat proper speed through belt and pulley systems 44, 45 theicbeam 38.lThe movable vmember of the clutch is `operated to close the clutch by afork 46 connected with the treadle 47.

The examining board 14 is formed in sections (Fig. 2) and whenthe maintable is extended or reduced in width one or vmore of these sections maybe added or removed;

at such times it will also be necessary toA change the beams and guiderollers Vfor ones of different lengths. 1

Having thus fully described myV invention what I claim and desiretosecure by Letters Patent is: Y K
